A normal and healthy pregnancy lasts for about 40 weeks. However, due to various factors, the labour may occur well before or after the estimated date. If the labour occurs before 37 weeks of pregnancy, the birth is considered to be premature, or preterm.
Classification:
Based on how early the baby is born, the baby is classified as:
- Late preterm: born between 34-36 weeks of pregnancy.
- Preterm: 24 - 34 weeks of pregnancy.
- Extremely preterm: born before 25 weeks of pregnancy.
- Women younger than 17 and older than 35 are at an increased risk of premature delivery.
- Having a previous premature birth.
- Pregnancy with twins or multiples often results in preterm delivery.
- Malnourished women are also at a higher risk of premature delivery.
- Women suffering from chronic conditions like high blood pressure or diabetes.
- Being underweight or overweight during pregnancy.
- Smoking, drug abuse, or excessive consumption of alcohol during pregnancy.
- Problems related to cervix, uterus, or placenta.
- Physical injury, accident, or some other kind of trauma.
- Women with a past history of miscarriages or abortions are more likely to go into labour prematurely.
- Excessive physical, mental, or emotional stress.
- Infections, especially in the lower genital tract often result in preterm birth.
- Women who conceive through in-vitro fertilization have a higher chance of premature labour as compared to others.
- An interval of fewer than six months between successive pregnancies.
